Do not give her the money unless you are prepared to give it as a gift. It would be futile to expect it to be a loan when you know you won't get it back. It is ok to say no, it is not your job to support her entertainment when she does nothing to earn money for herself. Another option is to have her do some work for you to earn it, but to do that work BEFORE you give her any money, because she will not fulfill her side of the bargain. If she does not want to earn it from you then it just shows how much she expects others to cater to her for doing nothing.

I've had severe depression for a large portion of my life. I also have social anxiety, PTSD, and a few other issues that I've been in therapy for in recent years....

My GUESS is that it isn't so much of her depression and anxiety (except for it not being controlled), so much that it is her just not being very mature, not making plans on how to pay for stuff, and not keeping her word.

She definitely won't like it when you say "no," she may even flip out at you each time you say it, but you must say it in order for her to learn something. She needs to see that in order to get something, she has to earn it and plan for it.

Go with your instincts tell her that if she wants to do things like privileges then she will have to raise it herself. If it's a need then you'll pay for it, but the concert is not a need.

Just say no really gently. Insist she can raise it herself and act positive no matter where the conversation leads.

don't let her borrow it... dude she's not your kid you don't have to let her borrow money or give her anything. who cares if she has anxiety or whatever what's the worst she can do just criticize you?

Just say "Sorry, no."
